This indicates that the injectors have maxed out and need to be bigger. Now FUELPW1 and FUELPW2 on my setup are different size injectors and don't have to have the same ms pulse width.īut I do expect that for two different RPM's with the same load (ie Alpha-N TPS Load/rpm map number 135.023 at 11,750 and 12,500) an injector would have the same pulse width.ĥms at 11,703rpm = 351 degrees and for the same load at 12,500 rpm I would expect the pulse width to be the same.īut here the pulse width has decreased as the rpm went up and 4.8ms at 12,500rpm = 360 degrees.
Selected two points on the Alpha-N, TPS/RPM Load map and checked the screen gauges at 11,750 and 12,500 rpm. I'm considering modifying the Series instruments - make the speedo stepper driven with multi-function warning lights, make the temp gauge driven from the MegaView, maybe replace the single charge light sector with a decent readable LCD, and add a MegaView readout somewhere (I have a decent 4x20 LCD in unobtrusive amber text on black which is plan A, location undecided as yet).Ī few other ideas but nothing very solid yet.To nights effort was about trying to figure out if I have the right size injectors and if I can make them do the job in less than 360 deg at max rpm.
These rule out things like small colour LCD's (unreadbale by day, annoying by night), touchscreens (unusable in a moving Series), and a fair few dedicated digital displays (LCD/OLED especially blue illuminated ones ) In keeping with the general Series 3 look (no carling switches, no f**ing blue LED's) Instruments readable in daylight and unobtrusive at night Robust components (must stand the interior being hosed out as a minimum) The MS, EDIS and relays/fuses will likely stay mounted on the ceiling. I may re-use the Series binnacle but with improved/enhanced switchgear & instruments. What I want to avoid though is going down the LCD screen route - at that point you may as well just nail a small laptop to the dash. I'm not about to fabricate a complete full-width dash, more just an instrument binnacle and/or switch panels where the driver goes.Īlthough I currently have an Acewell digital speedo/odo/fuel/lights gauges, I am seriously considerng replacing it with a DIY'd one based on the Megatune code as it's a short leap from Megatune to a digital dash.
